CLAMP PLATE Filed Feb. 24, 1928 Patented Jan. 7, 1930 UNITED STATES PATENT 'o rriclg I EDMUND w. RIEMENSCHNEIDER, or cannon, ,oHio, assrenon To run UNIonMErAI. MANUFACTURING COMPANY, or "CANTON, OHIO, A-CORPORATION orgo'nro CLAMP PLATE Application filed February 24, 1928. Serial No. 256,550.

adapted to'receive one fillet of the fluted pole l0 and having an angular face upon each side of said groove adapted to c-ontactwith the adjacent fillets of the pole, a U-shaped bolt being arranged to engirdle the pole, the ends thereof being arranged to be located through the clamp plate and through the cross arm to be supported thereby and to be attached thereto as by nuts or the like.

An embodiment of the invent-ion is illustrated in the accompanying drawing, in

which Figure l is an elevation of a fluted pole provided with cross arms attached thereto by the improved clamp plate;

Fig. 2, an enlarged sectional View take substantially on the line 22, Fig. 1;

Fig. 3, an elevation of the inner face of the clamp plate; and

Fig. 4, an end elevation of the same.

Similar numerals refer to similar parts throughout the drawing.

The improved clamp plate is adapted to be applied to fluted poles as indicated generally at 1 which may be of taperedtubular construction as shown in the drawing. 7 n

Cross arms 2, which may be of wood, are adapted to be firmly attached to the pole at any desired point along the length of the pole, for the purpose of carrying insulators 3 or the like to which wires may be attached.

One of the clamp plates, as indicated generally at 4, is provided for attaching each cross arm to the pole at any desired point along the length of the pole. This clamp plate may be of channel cross sectional shape having the upper and lower outturned flanges 5 between which the crossarm 2 may be re-.

ceived;

The inner face of the clamp plate maybe provided near its upper and lower edges with the projecting portions 6, each of which has the centrally located V-shaped 'grooVe7 and i the oppositely'disposed plane faces 8 and 8 in angular relation with each other.

-. In' attaching the cross arm to the fluted pole, the inner'face of'theclamp plate is positioned toward, the pole as best'shownin Fig.2, the fillet ofone flute only, as shown at A,'-beingreceived in the single'V-shaped groove 7 while the fillets of the flutes'at either side thereof,-as indicated at B,"'contactwith .theangular faces 8,whilegif additional faces 8 are provided,"the'next adjacent fillets contact therewith as indicated at C.

' A U-shapedbolt 9 mayengirdle the pole for drawing the clamp plate'tightlyagains't the same. The legs of thisbolt are extended through the elongated openings or slots 10in the plate andthrough the'cros'syarm,*nuts 11 upon the pole at the desired point.

. By providing elo ngated'o'pening's l0 inthe clamp plate, it willbe seen that thesame clampplate maybeused at diflerentpoints upon the tapered pole-orupon poleso'f-dif- 'ferent diameters, permittingthe use ofU- bolts of different sizesito conform to thediameter of'the pole, as indicated in v broken lines at 9 in Fig. 2.

being applied to the threaded-extremitiesTof the bolt for drawing the parts tightly toh gethe'r and clamping the arm and clamp'plate the clamp with the fillets A, B-B and C0 prevents movement of the arm in a horizontal plane, thus holding the arm rigidly in position upon the pole.

I claim 1. A clamp plate for a fluted pole, a pair of plane Ifaces iii-angular relation with each other upon the plate for contact with the.

outer .filletsljof two flutes of the pole, anda U-bolt connected with the plate adapted to engirdlev the pole and to clamp the plate against the pole, whereby the faces will maintain contact with said outerfillets for a considerable length of the pole.

and a U-bolt adapted to .engirdle the pole and to clamp the plate against the pole, the plate having elongated openings to receive the legs of the U -bolt whereby the plate may be attachedto different diameters of poles. 3. A clamp plate for a fluted pole, including a single vertical groove for engagement with the fillet of one flute only of the pole, 7 plane faces in angular relation with each" other upon the plate for contact with fillets ofotwo flutes of the pole, anda U bolt connected with the plate adapted to engirdle the pole and to clamp theplate against the pole, the plate having elongated openings: tore- V ceive the legs of the U-bolt whereby the plate may be attached to different diameters of poles, W v

'5. A clamp plate for a fluted pole including a single vertical groove for engagement with the fillet of one flute only of the pole,
